We're dividing 21854143 by 837 
We're looking to find how many times 837 goes into 21854143.

Advancing to step 1:
When dividing 2 by 837, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 837

On to step 2:
The number 837 fits into 21 0 times, leaving a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Take the next digit (8) from the dividend and append it to 21, then repeat: 218 / 837

Step 3:
When dividing 218 by 837, we get 0 with a remainder of 218.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 218 to get 218.
Append the next digit (5) from the dividend to 218 and continue with: 2185 / 837

Going ahead to step 4:
837 goes into 2185 2 times with a remainder of 511.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 1674 from 2185 and we're left with 511.
Append the next digit (4) from the dividend to 511 and continue with: 5114 / 837

Going ahead to step 5:
837 goes into 5114 6 times with a remainder of 92.
Write down 6 as next digit of the result. 
Result so far: 26.0
Subtracting 5022 from 5114 leaves us with 92.
Fetch the next digit (1) from the dividend, attach it to 92 and continue: 921 / 837

Going ahead to step 6:
The number 837 fits into 921 1 times, leaving a remainder of 84.
Use 1 as the next digit of our solution. 
Result so far: 261.0
The remainder is 84 after subtracting 837 from 921.
Grab the next digit (4) from the dividend, add it to 84, then carry on: 844 / 837

Step 7:
The number 837 fits into 844 1 times, leaving a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 2611.0
If we subtract 837 from 844, we get 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 837

Advancing to step 8:
The number 837 fits into 73 0 times, leaving a remainder of 73.
The next digit of our result is 0. 
Result so far: 26110.0
The remainder is 73 after subtracting 0 from 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 9:
837 can be fit into 730 0 times, resulting in a remainder of 730.
Record the quotient 0 as the next digit in the result. 
Result so far: 26110.0
Deduct 0 from 730 and we're left with 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Moving on to step 10:
7300 divided by 837 is 8 with a remainder of 604.
Record the quotient 8 as the next digit in the result. 
Result so far: 26110.08
Subtract 6696 from 7300 to get 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

On to step 11:
When dividing 6040 by 837, we get 7 with a remainder of 181.
Write down 7 as next digit of the result. 
Result so far: 26110.087
The remainder is 181 after subtracting 5859 from 6040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Moving on to step 12:
1810 divided by 837 is 2 with a remainder of 136.
Put 2 as the next digit of the answer. 
Result so far: 26110.0872
The remainder is 136 after subtracting 1674 from 1810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

On to step 13:
837 goes into 1360 1 times with a remainder of 523.
Write down 1 as next digit of the result. 
Result so far: 26110.08721
Subtracting 837 from 1360 leaves us with 523.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

Going ahead to step 14:
When dividing 5230 by 837, we get 6 with a remainder of 208.
The next digit of our result is 6. 
Result so far: 26110.087216
Subtract 5022 from 5230 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 15:
The number 837 fits into 2080 2 times, leaving a remainder of 406.
The number 2 becomes the next digit in our result. 
Result so far: 26110.0872162
The remainder is 406 after subtracting 1674 from 2080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Step 16:
The number 837 fits into 4060 4 times, leaving a remainder of 712.
Record the quotient 4 as the next digit in the result. 
Result so far: 26110.08721624
If we take 3348 away from 4060, we end up with 712.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

The final outcome is 26110.08721624, with a leftover of 7.12e-07.
